java - 将参数传递给参数

Question

我创建了一个类“Item”来实现 Parcelable 并设置他的构造函数

public Item(Parcel in) {
    this.mName = in.readString();
    this.mFilePath = in.readString();
    this.mId = in.readInt();
    this.mLength = in.readInt();
    this.mTime = in.readLong();
}

我的问题是，当我使用该类时，我不知道要传递什么参数，如下例所示:

 Item item = new  Item(//What to put her!); 
    item.setId(c.getInt(c.getColumnIndex("_id")));
    item.setName(c.getString(c.getColumnIndex(DBHelperItem.COLUMN_NAME_RECORDING_NAME)));
    item.setFilePath(c.getString(c.getColumnIndex(DBHelperItem.COLUMN_NAME_RECORDING_FILE_PATH)));
    item.setLength(c.getInt(c.getColumnIndex(DBHelperItem.COLUMN_NAME_RECORDING_LENGTH)));
    item.setTime(c.getLong(c.getColumnIndex(DBHelperItem.COLUMN_NAME_TIME_ADDED))); 
return item;

Answer 1

Parcel.writeStringArray

使用 Parcel.writeStringArray bundle 字符串，然后将其传递给构造函数
